Use the latest Uniform Solar Energy and Hydronics Code to provide a safe and functional solar energy system with minimum regulations.
Users of the 2015 Uniform Solar Energy Code are urged to strive for not just the minimum good solar energy system, but to keep the consumer in mind. With the exception of “high use and wear portions” of the system, the solar energy system should have the same life as other components of the building.
Here you’ll find what the code requires for all solar energy construction and installation and repair. This Code applies to the erection, installation, alteration, addition, repair, relocation, replacement, additions to, use or maintenance of the solar systems.
